Abstract
Description
Technical Field
[0001] This utility model relates to the field of baby diaper technology, specifically a breathable baby diaper. Background Technology
[0002] Disposable diapers are a common hygiene product for infants and young children. The main structure of a disposable diaper usually includes a cover and a core, and disposable diapers are single-use items.
[0003] Currently, there are many types of baby diapers available. For example, Chinese patent number CN202322156152.8 describes a breathable baby diaper. This patent includes a diaper body with a core installed at the top. The exterior of the diaper body is provided with a breathable component for air circulation. The breathable component includes two transfer chambers, respectively located inside the front and rear ends of the diaper body. Antibacterial non-woven fabric is provided in the center of each transfer chamber. This invention utilizes the connection between multiple internal and external air holes on the breathable component. This design allows air to circulate through the inner and outer pores, ensuring comfort for infants wearing the diaper. It also utilizes dustproof gauze to block dust, antibacterial non-woven fabric to block bacteria, and moisture-absorbing fabric to absorb moisture, thus ensuring the cleanliness of the air passing through and preventing harm from bacteria and dust. However, since the liquid storage capacity is similar to traditional diapers, it is not suitable for prolonged wear. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a breathable baby diaper with a strong liquid storage capacity, thus solving the problem of the diaper's liquid storage capacity being effective.
[0005] To achieve the aforementioned goal of strong liquid storage capacity, this utility model provides the following technical solution: a breathable baby diaper, comprising a diaper main body, wherein an absorbent mechanism is provided on the diaper main body;
[0006] The absorbent mechanism includes two expansion chambers. The main body of the diaper has two expansion chambers inside. Each of the two expansion chambers contains two absorbent expansion sponges. Inside the main body of the diaper and between the two absorbent expansion sponges, there are sequentially arranged an impermeable bottom layer, an activated charcoal deodorizing layer, a wet paper layer, and a flexible skin-adhesive layer.
[0007] Furthermore, the bottom wall of the impermeable bottom layer is bonded to the inner bottom wall of the diaper main body, the top wall of the impermeable bottom layer is bonded to the bottom wall of the activated charcoal deodorizing layer, the top wall of the activated charcoal deodorizing layer is bonded to the bottom wall of the wet paper cloth layer, and the top of the wet paper cloth layer is bonded to the bottom wall of the flexible skin-adhesive layer.
[0008] Furthermore, the upper and lower ends of the diaper's main body are respectively provided with two first guardrails and two second guardrails.
[0009] Furthermore, each of the first enclosure fabrics is provided with an inner hook and loop fastener surface, and each of the second enclosure fabrics is provided with an outer hook and loop fastener surface that is adapted to the inner hook and loop fastener surface.
[0010] Furthermore, breathable mesh is provided on both the upper and lower ends of the main body of the diaper, located at the absorbent mechanism.
[0011] Furthermore, the main body of the diaper is composed of two layers of non-woven fabric.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] 1. This breathable baby diaper features an absorbent mechanism. When a baby urinates, the soft skin-contact layer absorbs the waste liquid first. Then, because an absorbent sponge and a wet paper layer are connected below the soft skin-contact layer, these layers absorb all the moisture from the soft skin-contact layer, ensuring dryness. An activated charcoal deodorizing layer effectively removes odors from the water in the absorbent sponge and wet paper layer. Finally, a liquid-impermeable bottom layer ensures the diaper remains airtight after absorbing moisture, effectively preventing water escape. Overall, this mechanism not only has strong water retention capacity but also effectively prevents water loss and eliminates odors, making it highly practical. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 In this embodiment, a breathable baby diaper includes a diaper main body 1, on which an absorbent mechanism 2 is provided;
[0021] The absorbent mechanism 2 includes two expansion chambers 201. Two expansion chambers 201 are located inside the diaper main body 1. Each expansion chamber 201 contains two absorbent expansion sponges 202. Inside the diaper main body 1, and between the two absorbent expansion sponges 202, are sequentially arranged an impermeable bottom layer 203, an activated charcoal deodorizing layer 204, a wet paper layer 205, and a flexible skin-adhesive layer 206. The bottom wall of the impermeable bottom layer 203 is bonded to the inner bottom wall of the diaper main body 1; the top wall of the impermeable bottom layer 203 is bonded to the bottom wall of the activated charcoal deodorizing layer 204; the top wall of the activated charcoal deodorizing layer 204 is bonded to the bottom wall of the wet paper layer 205; and the top of the wet paper layer 205 is bonded to the bottom wall of the flexible skin-adhesive layer 206. When a baby urinates, the waste liquid is first absorbed by the flexible skin-adhesive layer 206. Then, because the flexible skin-adhesive layer 206 is connected to the absorbent expansion sponge 202 and the wet paper cloth layer 205, the absorbent expansion sponge 202 and the wet paper cloth layer 205 will absorb all the moisture in the flexible skin-adhesive layer 206 to ensure dryness. Then, by setting an activated charcoal deodorizing layer 204, this layer can effectively remove the odor caused by the water in the absorbent expansion sponge 202 and the wet paper cloth layer 205. Finally, by setting an impermeable bottom layer 203, this layer can ensure the tightness of the diaper after absorbing moisture and effectively prevent moisture from escaping. Overall, this mechanism not only has a strong water storage capacity, but also effectively prevents moisture from escaping and removes odors, making it highly practical.
[0022] In the case implementation, the upper and lower ends of the diaper main body 1 are respectively equipped with two first guardrails 3 and two second guardrails 4. Both the first guardrails 3 and the second guardrails 4 have elasticity. This design can be used for babies of different stages and has strong applicability.
[0023] In the implementation of the case, each first enclosure fabric 3 is provided with a Velcro inner hook surface 6, and each second enclosure fabric 4 is provided with a Velcro outer hook surface 7 that matches the Velcro inner hook surface 6, and the two can be glued together, thereby facilitating wearing and fixing.
[0024] In the case implementation, breathable mesh 5 is provided on both the upper and lower ends of the diaper main body 1 and the absorbent mechanism 2. This design not only improves its breathability, but also effectively prevents external impurities from entering.
[0025] In the case implementation, the main body of the diaper 1 is composed of two non-woven fabric layers. The non-woven fabric layer can improve the breathability of the diaper, allowing water vapor to circulate to the outside of the diaper, timely expelling moisture and heat, effectively reducing the chance of eczema, and making it soft, comfortable and basically non-irritating to the skin.
[0026] When implementing this procedure, please follow these steps:
[0027] 1) Firstly, when the baby excretes, the soiled liquid will be absorbed by the flexible skin-adhesive layer 206.
[0028] 2) Then, since the flexible skin-adhering layer 206 is connected to the water-absorbing and expanding sponge 202 and the wet paper cloth layer 205, the water-absorbing and expanding sponge 202 and the wet paper cloth layer 205 will absorb all the moisture in the flexible skin-adhering layer 206 to ensure its dryness.
[0029] 3) By setting up an activated carbon deodorizing layer 204, this layer can effectively remove the odors produced by the water quality in the water-absorbing and expanding sponge 202 and wet paper cloth 205 layers.
[0030] 4) Finally, by setting an impermeable bottom layer 203, the diaper can ensure its tightness after absorbing water, effectively preventing water escape.
[0031] In summary, this breathable baby diaper, through the inclusion of an absorbent mechanism 2, allows the soft skin-contact layer 206 to absorb the liquid during excretion. Then, because the soft skin-contact layer 206 is connected to an absorbent sponge 202 and a wet paper cloth layer 205, these layers further absorb all the moisture from the soft skin-contact layer 206, ensuring dryness. Furthermore, the activated charcoal deodorizing layer 204 effectively removes odors from the water within the absorbent sponge 202 and wet paper cloth layer 205. Finally, the impermeable bottom layer 203 ensures the diaper remains airtight after absorbing moisture, effectively preventing water loss. Overall, this mechanism not only has strong water retention capacity but also effectively prevents water loss and deodorizes, making it highly practical. It addresses the issue that, similar to traditional diapers, the limited liquid capacity makes them unsuitable for prolonged wear.
